I currently have a LAN set up (no internet) through a switch to connect my PC to my arduino with ethernet shield. On my PC I have apache running with a simple php script, and I would like to be able to get data from there on the arduino. My problem is that even though I have everything set up, I can't seem to connect to the PHP script from any computer on the LAN other than the computer running apache.

The IP of the PC is 192.168.0.2, and I have the httpd.conf file set to LISTEN 192.168.0.2:80. The IP of the arduino is 192.168.0.3, and when it is connected I can successfully ping that IP address, but I am unable to connect to the server. I also tried hooking up a laptop to the LAN and was again unsuccessful in connecting to the PHP script, but could ping the IP just fine.

As you can't access the php from any computer (or arduino) other than the webserver then it suggests its the problem is with the webserver or router

* It could be the router - check the manual for the router and see what it says about firewall/port mapping/port blocking (personally I doubt it is this, but worth checking)* Check the webserver is serving other pages - try a standard html page (helloworld.html or something) in the same folder as the php and see if you can get it. If not you need to check the folders the webserver is pointing to (see WAMP documentation)* Make sure you have the right site enabled - are you still running the default apache site or have you set up a different one (this basically the same as the folders above) (see WAMP documentation)
